High Quality Content by WIKIPEDIA articles! The Atlantean language is a constructed language created by Marc Okrand for Disney`s film Atlantis: The Lost Empire. The language was intended as a possible "mother language" and was therefore crafted to include a vast Indo-European word stock with its very own grammar, which is at times described as highly agglutinative, inspired in Sumerian and North American languages. The decision of this language being a possible "mother language" was actually a decision made by the script-writers of the movie, and not by Marc Okrand himself, who followed this presumption upon its creation.
